Septic tank abandonment procedures required by Pennsylvania law
Pumping out the tank is just the first step. Pennsylvania regulations require the tank to be crushed in place or completely removed.

This prevents groundwater contamination and meets PA DEP abandonment standards.
Excavation challenges in O’Hara’s hilly terrain
Properties along Saltzman Road or near Squaw Run often require deep excavation due to the area’s rolling hills. A 6-foot depth may be needed where the sewer main sits below road grade.

Trenchless vs. traditional excavation methods
Trenchless technology works well for straight runs under driveways or mature landscaping. Directional boring costs $12-$20 per foot but avoids destroying existing hardscaping. Traditional excavation at $8-$12 per foot works better for properties with many turns or obstacles. The choice depends on your property layout and whether you have mature trees along the planned route.
Permit timeline and inspection requirements
The permitting process takes 2-4 weeks after submitting plans to ALCOSAN and the township. Inspections occur at three stages: after excavation, after pipe installation, and after final connection. The Allegheny County Health Department conducts the final inspection to ensure proper slope and watertight connections. Missing an inspection can delay occupancy by weeks.
Landscaping and driveway restoration costs
Excavation destroys grass, shrubs, and any surface features in the path. Sod replacement costs $1-$2 per square foot. Driveway patching with asphalt runs $3-$5 per square foot. Some homeowners budget an additional 15-20% of the total project cost for complete landscape restoration.

Environmental benefits of connecting to public sewer
Public sewer systems provide better treatment than most septic systems, reducing nitrogen and bacteria in local waterways. This helps protect Squaw Run and other tributaries that flow into the Allegheny River. The centralized treatment also prevents the gradual soil contamination that occurs with aging septic systems.
